無ran酶純水

① 下列關於二倍體高等植物細胞有絲分裂的敘述，不正確的是

【答案】B
【答案解析】試題分析：植物細胞有絲分裂需要線粒體提供能量，核糖體合成蛋白質，高爾基體形成細胞壁，A正確；要進行DNA復制，轉錄和翻譯，因此需要DNA解旋酶、RAN聚合酶、等酶的參與，無DNA水解，無需DNA酶，B錯；在細胞分裂的間期有同源染色體的復制，C正確；分裂後期染色體數暫時增倍，DNA在間期已經復制，末期隨著細胞一分為二，染色體和DNA數都減半，D正確。
考點：本題考查細胞有絲分裂相關知識，意在考查考生能理解所學知識的要點，把握知識間的內在聯系能力。

② 求翻譯一篇英語

The Coca-Cola Company (Coca-Cola, The specific NYSE: KO) is a Company headquarters is located in The United States in Atlanta, Georgia multinational drinks manufacturers. Independent proction of the procts have coke, Sprite, fanta, marked, Glaceau vitaminwater, beauty of fruit series, QOO queer juice series, fly snow mineral water, pure water ice dew series series, the earth and heaven, and the valley of haze of tea series, etc. And nestle cooperative proction of refreshing tea, a nestle canned nestle coffee etc.

Although many different about "Coca-Cola" the legend of the name, in fact, "Coca-Cola" English name is by pemberton was assistant accountant named Robinson and partner. He is a classical calligrapher, he thinks "two capital C word will look nice", so the Coca-Cola "with", "Coca" Coca leaves promotes practice is the spices, "Cola" is coke out of the fruit components. "Coca-Cola" trademark DuoNian to have been no change.

"Coca-Cola" the origin of the Chinese name

"Coca-Cola" this name, already "delicious" also "coke", not only keep English sound, still more interesting than English. The Chinese name is by scholars JiangYi translation to come out. "Coca-Cola" in "1920 s proction but not in Shanghai has officially Chinese name. At first use" Ke Ke chew wax ", result because of improper literally in the Chinese market and failed to success. [1] so, when "Coca-Cola" dedicated to the overseas business "Coca-Cola" export company in Britain, was for translation. Was study in Britain, and the JiangYi with "Coca-Cola" four word beat the other competitors took 350 pounds. [1].

Coke history

Coca-Cola was a doctor of invention, also can saying is he manufactured the coke. Once, he gave a patient a doctor, opened a bottle of potions, let patients after coming home taking, results, when he ready to rest, suddenly night the man again come, and are glad to, will own the VAT handed to the doctor, filled with full requirements before a barrel, and a potion last time, just as the doctor muddleheaded ground did. The next day, he took a stronger player to come here, they pass their cups and bucket, rob to buy potions. The doctor was very strange, then ask why they every day to buy medicine, is it every family ill? People holding thumb praised the potion is very nice. Here The doctor confused: "no ill, why buy medicine every day? Is this the potions can cure, or delicious drink?" And so, he bold opened a "potions" factory, because this potion is very nice, people drink are extremely happy, he decided to call it "Coca-Cola", the unknown doctor, just because a bottle of potions, and then let his potions around the world. 1885, Georgia, USA "Dr. John Stith Pemberton. >. And invented the brunet syrup called pan burton French Wine coke (Pemberton 's Flench Wine Koka) in the same year the government issued a commissioner, so pan burton invention non-alcoholic Pemberton' s Flench Koka Wine. On May 8, 1886, pan burton doctor wanted to invent a drink, a kind of let many need compensatory nutrition people like to drink beverages. That day, he is prepared to stir the s Coca-Cola beverages, found it has a calming influence, refreshing, and ease headache, he will join the syrup and the liquid water, and then add ice, he tasted it, it's very delicious, but in the second cup, the assistant carelessly joined the carbonated water (soda water) (carbon dioxide + water) tastes better this time, partners (Flank M.L obinson) Robinson from two ingredients of syrup, stimulate the naming of inspiration, these two elements are Coca (Coca leaves and korah) (Kola) fruit, Robinson to neat and tidy, will the Kola change, and then in C K two words with a horizontal, and among Coca-Cola was born, and the first Coca-Cola sells for five cents.

④ 酶的本質是蛋白質和RAN,蛋白質的性質我們已經學過,有哪些性質呢

對於酶來說性質是：催化性、專一性、條件溫和性、高效性。一般很少去說蛋白質的性質。蛋白質的結構決定其功能，每種蛋白質功能不一樣，性質也不一樣。比如載體蛋白具有專一性。蛋白質容易高溫變性失去其功能

⑤ 當RAN聚合酶到達終止密碼子時，RNA合成結束 這句話哪裡錯了

RNA合成的開始與結束對應起始子與終止子，因此RNA聚合酶到達終止子的部位時，RNA合成才結束。
多肽合成（翻譯）的結束才對應終止密碼子（且多肽的合成不需要額外的酶）

⑥ 原核生物RAN聚合酶的作用與結構

作用：轉錄,合成RNA
結構：核心酶a2bb』w
阿爾法亞基：識別和結合起動子
貝塔亞基：催化部位的主體,轉錄的起始和延伸
西格馬因子：轉錄起始,識別起動子
抑制劑：利福平,肝素

⑦ 純水摩托車是什麼意思

純水就是指走私的摩托車，這種車基本上都是二手舊車，車的來源不專明，比如有報廢車、盜屬搶車等，通過走私渠道進入國內，這種車上不能上牌，也不能合法上路，管的嚴的地方上路會被交警查扣。

1. 純水：從國外轉至國內港口的二手車，這些車大都是在兩年左右，成色都很好，價格高。

2.一般水貨：和上述的純水類似，但一般都是車齡較老的，10年以內的，但是成色和保養還是不錯的，價格也比較高。

摩托車，由汽油機驅動，靠手把操縱前輪轉向的兩輪或三輪車，輕便靈活，行駛迅速，廣泛用於巡邏、客貨運輸等，也用作體育運動器械。從大的方向上來說，摩托車分為街車，公路賽摩托車，越野摩托車，巡航車，旅行車等。

⑧ C1酯酶是什麼

C1抑制物(C1INH)是血清中高度糖基化的一種蛋白質,含糖量高達35-49%。最初由Ranoff和lepow(1957)所發現,稱其為C1酯酶抑制劑,與引同時Schultze等則將其稱為α2神經氨酸糖蛋白。C1INH為一單鏈分子,由478個氨基酸殘基組成,分子量為104kDa,由478個氨基酸殘基組成,分子量為140kDa,鏈內有兩對二硫鍵(圖5-13)。C1INH調節的主要方式是,與活化的C1r或C1s結合形成穩定的復合物而導致C1絲氨酸蛋白酶失活。其作用機理是,C1INH通過提供一個酷似C1r或C1s的正常底物的序列為「銹鉺」(「t」),被c
1r或C1s裂解暴露出一個活性部位,然後再與C1r或C1s結合形成共價的酯鍵而發揮抑製作用。此外,C1INH還可防止在缺乏抗體時,C1以很低但仍有一定速率出現的自發激活。正常情況下,血液中的大多數C1可被7倍於其克分子濃度的C1INH所結合,以防止C1由於構象改變而引起的自發激活。但C1同抗原、抗體復合物的結合,可使C1從C1INH的抑製作用中而獲釋。除上述作用外,C1INH還可抑制凝血因子Ⅻa、Ⅺa、激肽釋放酶及纖溶酶,因而其在凝血、激肽和纖溶系統中也有重要的調節作用。

⑨ DNA是否是一種酶

DNA不是酶，DNA可以控制酶的合成，是一種遺傳物質。絕大多數的RNA不是酶，但有少數的RNA是酶
